Dual Fuel Melting Furnace

[Carlos B]

Hi ViktorP you may have missed that I use two different burners. The Riel type burner is an atmospheric burner, does not require a fan and burns propane only. The dual fuel burner requires a fan, in propane mode to mix air and direct the mix down the burner tube, in the oil mode the air blast atomizes and mixes air at the burner nozzel.Thick motor oil requires elevated temps. and some press. at the burner. I painted my tank black to heat up on a sunny day and I use a magnetic block heater to get the temp up to around 100*F. I hung the tank from the eave of my workshop to pressurize the burner feed. At 10' I get a little less than 4 psi at the burner. Its a little tricky to set up but runs good when set up right. This will point you in the right direction but you'll need more info. a good place to start is Lionel Olivers site "Backyard Metalcasting .com".
